Seen Salcey Forest under rotting wood (probably oak) 8th March 08.

Size - very tiny, approximately 2.5mm long excluding legs. I have several pics of this individual and they all show legs that are a light colour near the body and darker toward the ends.

Visually I thought it looked quite like Dipoena inornata but would appreciate confirmation or correction.

Any other shots (if they are different) would be useful.
Still going through my books, though I don't think its Dipoena inornata, but we'll see after I've had a good search.

Thanks Venger. Here's a pic from another angle:

It's a member of the Robertus genus, if you look carefully you can see 3 pairs of impressed red spots on the abdomen. Not sure which species though as they all look very similar, but it's probably Robertus lividus as that is most common.

Wow Venger that's really well spotted (no pun intended

). I had to really look hard - after first checking out an image of R. lividus - to see where to look for the red spots.

Thanks again for your help.
